FERTILIZING ATTACHMENT FOR. SEED-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 319,893, dated June 9, 1885.

Application filed August 23, 1884. (No model.) I

i To all whom/ it may concern:

Be it known that I, AUSTIN C. EVA-NS, a citizen of the United States, residing at Springfield,in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Fertilizing Attachments for Seed-Planters; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it ap ertains to make and use the same, reference Eeing had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in fertilizing attachments for corn-planters.

My invention relates to that class of fertilizing attachments in which the fertilizer-dust is carried out of the hopper by a toothed disk rotating in a horizontal plane over the bottom plate or floor of said hopper; and it consists in the extension of said floor outside the hopper so as to form a recess or floor-space within the top of the discharge-tube. The bottom plate may be cast in a single piece with the discharge-tube; or the latter may be constructed separately with the floor-spacein it and attached to the hopper. The object is to prevent the fertilizer-dust from escaping through the discharge-hole in the latter. in a continuous stream by allowing it to collect on this floor-space in the discharge-tube outside and build up in a mass thereon in front of the hopper-opening during the operation of filling the hopper or when the machine is not in operation. My invention comprises also an agitator and crusher, which is pivoted to the top of the feed-disk and operates over the latter.

Figure 1 is a top view of an open fertilizerhopper with my improved sowing devices. Fig. 2 is avertical section of the same through line as of Fig. 1,. Fig. 3 is a transverse section of the hopper, showing a view of the feriilizing devices from the rear. Fig. 4 is atop View of the discharge-tube, a horizontal section of the front of the hopper, and a section of the disk enlarged. Fig. 5 is a perspective view of the same. Fig. 6 is an enlarged view of a portion of the disk, showing the shape of the teeth, one of which is seen in this view.

of the disk G. The cut-off 0 consists of a .long fiat bar standing vertically, and bent or Fig. 7 is a top View of a separate dischargetube.

A is the fertilizer-hopper, which is of the usual square form, and tapering on one side from top to bottom.

B is the bottom plate, which is cast in one piece with the discharge-tube E. The floor of the hopper extends outside of the latter into the top of the tube E, as seen in Figs. 4 and 5, the purpose of which will be explained hereinafter.

The front wall, a, of the hopper has a recess on the outside, with an opening, a, through the same wide enough to allow the teeth and a part of the body of the disk to pass through it. The face of this opening is tangential to the line of the wall a, so that the cut-off c,which closes the opening, stands at nearly right angles across the orbital line twisted near the lower end to allow it to conform to the opening, and extends through an inclined loop, b, on the inside of wall a.

Forward of the opening a, as seen in Figs. 4 and 5, in the direction of rotation of disk 0, is a triangular projection, to, the side a of which forms a fixed cut-off, as the incline a extends down as near as possible to the top surface of the'disk, and effectually cleaning the top surface of the latter and causing the fertilizer-dust to drop into the dischargetube'E. It will be noticed by reference to Figs. 4. and '5 that a part of the body of disk 0 rotates outside of the hopper as well as its teeth e e, and upon the surface of this part of the disk adjacent to the teeth a portion of the fertilizer-dust is carried, so that the inclined wall a of the projection a scrapes ofi all that is carried outside by both the body and teeth of the disk.

The disk G is cast with an upright boss, (1, from which projects a vertical pin, (1, and upon this latter is pivoted a long horizontal lever, D, about the middle of the latter, as seen in Figs. 1,2, and 3. The boss (1 is located outside of the center of the disk, as seen in the vertical section, Fig. 2, which shows the vertical shaft 0 of the latter giving an eccentric motion to the lever, the rear end of which extends r00 through a hole, 6, in the post e on the bottom plate, B, just outside of the orbit of the disk, as seen in Figs. 1 and 3. The lever D is placed diagonally across the hopper, and its front end is curved downward and forward so as to be brought as near to the lower end of 'tilizer-dust contained in the hopper is drawn from the opening by the disk 0, the front end b of the lever D is thrown forward to the lower end, 0, of the cutoff c, or nearly so, and aids in forcing the substance toward the disch arge-hole,besides catching and crushing the lumps. The cut-01f can be raised or lowered and held in adjustment by a bolt'and thumbnut, h.

The form of the teeth e'of disk 0 are seen in the View, Fig. 6, and also in Figs. 4 and 5. The tooth is triangular in cross-section, and is longer on the face side 6 than on the rear 6'. The face is of the full thickness of the disk, and from thelower edge, f, to the rear edge, 6', it is beveled or inclined upward so that the latter edge is sharp. The object in thus forming the tooth is to allow it to be more readily freed from the fertilizer substance collected from the face of one tooth to the rear of the next, and also to lessen the friction. The view, Fig. 6, shows the tooth from the under side, f. The end of the tooth is beveled or inclined toward the rear, which causes the fertilizer substance to drop more readily from the teeth as it is carried over the dischargetube.

Fertilizing attachments in which a toothed rotary disk operates to carry the fertilizer from the hopper to the discharge-tube have been before used, and I do notclaim such construction, nor do I make claim to a toothed disk in combination with a cut-off, either fixed or adj ustable; but where the teeth only of the disk operate to carry the fertilizer in a horizontal toothed disk the adjustment required to vary the quantity must necessarilyv be not only difficult, but quite limited.

1. In a fertilizingv attachment for a' cornpla-nter having its discharge-tube outside the hopper, a floorspace or recess in'the top of said discharge-tube to catch and retain the fertilizer-dust and allow it to build up in front of the hopper-opening, and'thus prevent'its escape through the discharge-tube while filling said hopper.

2. In a fertilizing attachment for a cornplanter, the combination, with the hopper having an opening in its side wall-for the sowing-disk, of a discharge-tube provided with a recess or floor-space in the top of the same, to allow the fertilizer-dust to catch thereon and build up in front of said hopperopening, for the purpose set forth.

3. In a fertilizing'attachment, the combination, with the hopper having the dischargeopening extending over the teeth and a part of the body of the disk, and the cut-off and means for adjusting the same, of the toothed horizontal disk operating in part through said opening, and the agitator consisting of the oscillating lever extending over said disk,

' pivoted to the latter outside of the center of the same, the forward end of said lever being bent downward and to one side toward said cut-off, and its rear end extending through a hole in a fixed post' on the bottom plate, whereby an eccentric motion is given to the front end of said agitator by the motion of the disk, causing it to thoroughly stir the fertilizer-dust and to crush any lumps therein, as set forth.

4. In a fertilizing attachment, the eombina tion of the hopper, the feed-disk rotating therein, and the agitator pivoted to the latter outside of the center of the same and extending across said hopper in a plane above said disk, its rear end being inserted through a post on the bottom plate and its front end bent downward and forward to agitate the fertilizer and crush the lumps in the same, substantially as set forth.

5. In a fertilizer-disk, the tooth 6, having its face 'of equal thickness with said disk and beveled on the under side from the lower edge of said face to the rear edge of saidtooth, and having its point beveled or inclined toward the rear to facilitate its operation in collecting and discharging the fertilizer substance, as set forth.

' 6. The" combination, with the horizontal rotating feed-disk, of the agitator extending over the same and pivoted about midway of its length thereto, its rear end being loosely inserted through a hole at a fixed point within the hopper to allow it to have a backward,

forward, and lateral motion, while its free end is adapted to move eccentrically to the disk to stir the fertilizer-dust and crush lumps in the same.

In testimony whereof I aflix my signature in presence of two witnesses.
